I've seen more success using bent pipe in this arrangement...

The top of the tube has to be way above the waterline... As the boat goes along the rear facing end of the tube outside the boat creates suction, and pulls out any water in the boat.

Well you can use thinner pipe and tighter bends... It's only a laptop pad drawing on paint ;)

When you install the backwards slanted tube in the bottom, out of the propwask, nobody will see it and it'll work even better.
(distinctively better than a forever leaking autobailer...)

Please seal the internals agains water.

where it is now is fine  :-)) try to keep up hill flow to a minimum and the tubing short as possible but still allowing for nice curves no sharp kinks.

Hi Going :

Mtroniks G2Hydra50 combo , will water cool motor, !!! " At least thiis will work, !!! this will give a good model speed,


 
Code: G2Hydra50c
50A Waterproof brushless speed control and motor set for model boat



The Genesis Hydra50 combo is a Forwards and Reverse Brushless Speed Control comlete with high power 600 can size inrunner motor designed specifically for use in scale RC boats.

The Genesis Hydra50 has a 50Amp Brushless motor limit, this is a rough equivalent to a standard, stock 600 or 700 can size brushed motor.

The Genesis Hydra50 Brushless speed control has been designed to fit straight into any RC model boat as a direct replacement for your Brushed speed control and motor. The set up is a no nonsense, one-step procedure making it very easy to get up and running within minutes! The Genesis Brushless Speed Controls designed for use in RC boats are all 100% waterproof giving you that extra peace of mind should the worst happen and you have to retreive your model from the graveyard under the pond!!

The Genesis Hydra50 benefits from 5 years worth of research and design work carried out by the Mtroniks design team with help from a few well known RC scale sailors. What this has resulted in is a Sensorless Brushless Speed Control that works and feels just the same as a Brushed Speed Control, giving you absolute control over the throttle with very smooth acceleration and the added bonus of longer run times when compared to Brushed Speed Control equivalents!

The 600can inrunner motor is 2100KV which equates to 2100 revs per volt (of your battery pack) for example, 24000rpm when run on a 12V battery.


Genesis Hydra50 features:

Easy one-step set up
Smooth controlable acceleration
5 to 10 cells NiCAD or NiMH
2-3 cells Lipo
6-12V Lead Acid
Automatic sensing of number and type of cells
Current limit cut-off
3A Hyper BEC
3 Internal Schottky diodes
Auto cut-off computer
Dimensions:-42mmx27mmx24mm
Weight:-60g
100% Waterproof
The Genesis Hydra50 speed control is capable of an average discharge rate of 45A and a peak discharge rate of 50A making it a very capable & attractive option at such a low price! Ideal for your first steps into the world of Brushless marine modelling!
The 'return to base' software upgrade enables the user to return their ESC to us to have the onboard software u
